Abstract: An adapter for rotatably connecting a sprinkler head to a water-transporting standpipe having a cylindrical upper end. The adapter includes three parts: a cup-like base adapted to rest on the upper end of the standpipe in sealed fashion, a male stem adapted to rotatably and scalingly seat in the cup-like base, and an oversleeve adapted to fit over the stem and the base and to be locked to the upper end of the standpipe by threaded connection such that a portion of the male stem protrudes from the oversleeve to be secured to the sprinkler head for rotation therewith. The adapter is sealed at several points internally to positively prevent water leaks, and is easily disassembled for replacement, repair, or cleaning, by hand or with simple hand tools, since no permanent connection is required between the adapter, the standpipe, and the sprinkler head.

Abstract: A truck having a material spreader and a control mechanism to regulate the velocity of materials ejected from the material spreader. The material spreader includes a material guider to guide the trajectory of substantially all the materials in a direction substantially opposite the direction of forward movement of the truck. The control mechanism includes a velocity sensor adapted to detect the velocity of the truck and to send a signal indicative of the truck velocity to a velocity controller. The velocity controller sends a signal to the material spreader which is dependent on the truck velocity to control the velocity of the materials ejected from the material spreader. The material spreader is mounted to the truck to allow the material spreader to be moved between a non-operational and operational position. The material spreader is also mounted to allow for lateral and/or upward movement upon encountering a predetermined force.

The second piece is movable at will, with respect to the body or first piece, in an X-direction, wherein the X-direction is different from a Y-direction defined as the fluid product outlet direction of the jet or spray of the fluid product. The second piece is movable in order to clean the inlet conduit.

Abstract: In a sprinkler system for warehouse freezers or other cold environments, a sprinkler system piping connected to a water supply through a check valve and extends through a freezing cold environment to sprinkler heads positioned to discharge extinguishant. The sprinkler system piping within the cold environment is filled with a solution of potassium lactate. When a fire occurs causing one or more of the sprinkler heads to be activated, the sprinkler heads will discharge the potassium lactate onto the fire. This action will reduce the pressure in the sprinkler system piping bellow that of the water supply so that water flows from the water supply through the sprinkler system piping through the activated sprinkler heads to be discharged upon the fire.

Abstract: The present device provides a fuel injector including a two-input, self-triggering monostable driver circuit for an electromechanical valve is disclosed. Upon receipt of an initiation signal, the driver circuit generates a predetermined current profile in a coil. A current sensing mechanism senses the current flowing through the coil, enabling a current threshold generator to detect a preset peak current threshold state. Upon detection of the preset peak current threshold state, the current threshold generator establishes a new hold current threshold state in the coil. A rapid decay generator forces a rapid transition from peak current to hold current within the coil. The hold current is maintained within preset hysteretic limits until the valve cycle is terminated by removing the initiation signal from the inputs.

Abstract: The spray nozzle comprises a mixing chamber into which a liquid, forming a first and a second liquid stream, can flow through two inlet openings and which comprises an outlet opening, disposed downstream, for a spray jet. A mixing chamber wall acts as a guide surface for the liquid streams and is shaped at the outlet opening such that the liquid streams meet at an angle at the outlet opening and then form the spray jet. Given an angle of impact of approximately 90°, this spraying process delivers droplets with a high level of kinetic energy and a broad uniform fan-out of the droplet paths. Large areas can therefore be uniformly sprayed with the spray nozzle from a considerable distance.

Abstract: A wildfire protection system has rotating sprinklers (1) on sprinkler legs (2) positioned temporarily or indefinitely as needed on roofs (10) with the sprinkler legs resting on opposite slopes (6) from a ridge (5) of the roof and removed for sprinkler irrigation or easily disassembled for compact storage when not in use for wildfire protection. The rotating sprinklers can wet not only roof tops but also nearby trees (13), shrubs (14) and areas for protection against flying sparks and burning particles. The rotating sprinklers are preferably a low-weight plastic type and the sprinkler legs are preferably four low-weight plastic members that intersect at a series connection for garden-hose water supply to one or more of the rotating sprinklers. The rotating sprinklers are saddled on a roof top with two of the sprinkler legs placed on each of two opposite roof slopes. Low weight of the rotating sprinklers allows them to be placed easily on roofs with access by ladder or structured to be positioned indefinitely.

Abstract: A vehicle washer nozzle liquid spray system having a source of washer liquid under pressure, a fluidic oscillator comprising a housing and a fluidic insert having a power nozzle, an oscillation chamber having an upstream end coupled to the power nozzle for issuing a jet of washer liquid into the oscillation chamber and a downstream end having an outlet aperture for issuing a jet of wash liquid to ambient, and side and top and bottom walls, an oscillation inducing silhouette in the oscillation chamber for causing said jet of wash liquid to rhythmically sweep back and forth between the sidewalls in the oscillation chamber. Top and bottom walls of the oscillation chamber first diverge for a predetermined distance in a downstream direction and then converge towards each other through said outlet aperture. This enables the deflection angle to be adjusted for different vehicles uses and applications by changes to the fluidic insert without changes to the housing.
